  Target Milestone: ---

Application: dolphin (20.12.2)

Qt Version: 5.15.2

-- Information about the crash:
- What I was doing when the application crashed:
Had a directory open with a number of subdirectories. When I clicked the arrow
to expand each subdirectory, every other directory had the arrow rotate but did
not show the files in the directory. Then I used F5 to refresh and dolphin
crashed and the bug report assistant came up.

- Unusual behavior I noticed:

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
